This is a well-worn theme I know but I have a touch of tendonitis (again). I'm trying figure out whether it's just general over-use--guitar and computer--or if there is some connection to my recent purchase of an HJ-38 Stefan Grossman Martin--a fantastic sounding and looking guitar. I usually play OOOs and OMs so the deeper J size feels, well, bigger. Any thoughts or tips on adjusting technique, posture, etc, would be good to hear about.
If El McMeen's listening and I know he's familiar with the HJ-38: Any suggestions El?
